If a grid does not have a default view, the View Builder opens. In this case, you can click Add All to move all Available Columns to the Selected Columns list, then Save. Once a (default) view is saved, you will no longer be prompted.

NOTE: These steps are needed per grid, for example, Workspace > CRM > Constituents, Workspace > Fundraising > Gifts, etc.

In the grid, click on the View menu (the three dots) and select Save View As.

Either change the view name or accept the name and click Save. The view can always be renamed using the menu and selecting Rename.
